M, a solid cylinder (m=2.39 kg, r=0.123 m) pivots on a thin, fixed, frictionless bearing. a string wrapped around the cylinder pulls downward with a force f which equals the weight of a 0.870 kg mass, i. e., f = 8.535 n. calculate the angular acceleration of the cylinder.

The angular acceleration of the cylinder is 58.06 rad/s².

Explanation:

Given that,

Mass

Radius

Force

Weight

We need to calculate the angular acceleration of the cylinder

Using formula of torque

Where, F = force

r = radius

m = mass

Put the value into the formula

Hence, The angular acceleration of the cylinder is 58.06 rad/s².

the force required to move the cart is divided by three or 33.33 n.
